Abstract

634,067. Centrifugal separators. BERGES, A. C. March 30, 1948, No. 8981. [Class 23] A separator for paper pulp comprises a plurality of cylindrical vortex vessels 11, each having, at the lower end, a baffle 22 and a side outlet 24b for tangential discharge of dirt-laden liquid into a common collecting and further separating chamber 14 which is provided with an outlet 17 for clean liquid. Pulp is supplied to the tangential inlets of the vortex vessels by a distributing member 18, and cleaned pulp is collected from the vessel outlets 19 by an outlet head 20. Dirt collected in a sump 16 flows from a pipe 29. In a modification in which there are two vortex vessels a tangential pipe is provided at the top of the sump for introducing scavenging liquid. Specification 455,845 is referred to.
